"When a colony of honeybees swarm, it's nature's way of dividing on a large scale," Repasky said. "So, the old queen takes off with half the colony and they go looking for a new place to set up residence."

Some swarms can contain 25,000 to 30,000 bees. Repasky said he rescued a swarm like that last May.

He was called to remove the bees because they're a protected species that cannot legally be killed.

Repasky said this was his fourth airport call, so it's likely that there is a wild honeybee colony at the airport somewhere.

"On an average year, I'll rescue and relocate 25 to 30 honeybee swarms. This year, I did well over 75, and that was a function of the weather," he said.
